The mysterious Trader pays your island a visit every week in a large red submarine. The moment of arrival is every Friday at 7 p.m. and she departs on Sunday at 11 p.m. local time. The trader always offers Trader Crates and some extra offers as well. A red buoy in the water at your base shows the time until the trader arrives.
Trader Tickets are necessary for trading. Acquire tickets by earning Supply Chests and collecting your daily reward boats. Also you can buy more Trader Tickets from the Trader’s extra offers.
Trader Crates can be bought from the Trader by using Trader Tickets. The first one per week is always for free. The next one will cost you 3 Trader Tickets. Trader Crates can contain any possible reward from Resources, Power stones, Prototype Modules, etc. It will however always contain at least one Hero Token.
Use Hero Tokens to upgrade your Heroes abilities. They can be found at the Traders extra offers
Besides the Trader Crates the Trader will always offer three different extra offers which need to be traded with other types of resources instead of the Trader Tickets. Some of the extra offers can only be traded once, while other extra offers can be traded several times.
